The Khan Madrasa (theological school) is a peaceful 17th-century Koranic school open to non-Muslim travelers thanks to the tolerant atmosphere Special to Shiraz.
A four-Ivan plan and an interior courtyard surrounded by student cells on a double arch structure. The current decoration dates back to the 19th century. Moula -Sadra, the famous philosopher of the Safavid era, taught in this school.
In Koranic schools, apart from theology and Koranic sciences, students learn gnostics and jurisprudence, sharia law, and a preface of Classic philosophy and Platonism besides Islamic philosophy.

Madrasa seems not to be fully active, but you always find some smiling mullah in the courtyard to discuss a subject and ask some questions.
